Stepping up in the same colour and case shape
The neo-vintage rally aesthetic here is not a trend the design team landed on arbitrarily — the green tachymeter bezel, the deep British racing green dial and the rose gold-tone indices form a coherent set that collectors have picked up on, and the 8T63 movement behind it earns its place with a chronograph hand that steps in 1/5-second increments and carries a tactile, almost mechanical feel when you work the pushers. At 38.7mm with a 45.1mm lug-to-lug, this sits closer to a gentleman's sports watch than to the oversized end of the chronograph market, and it will lie flat and balanced on a smaller or average wrist in a way that many chronographs at similar ratings simply will not. The dial reads very differently depending on the light — near black in shadow, a sharp emerald in direct sun — which keeps it from being a one-note piece. The bracelet adjusts on standard pins rather than a micro-adjust clasp, so getting a precise fit takes a link or two of patience, but the three-fold push-button release is secure day-to-day. At 110 grams the whole assembly has enough presence on the wrist to feel considered without becoming heavy by afternoon.

Learn more about Seiko
Kintaro Hattori opened a watch and clock shop in Tokyo in 1881, aged twenty-one, and began manufacturing under the name Seikosha — roughly, house of exquisite workmanship — in 1892. The Seiko name appeared on watches from 1924.
The company's significance is that it broke the Swiss monopoly twice. First on precision: Seiko was appointed official timekeeper of the 1964 Tokyo Olympics and built the quartz chronometers and printing timers to do it, and in the 1960s its movements placed highly at the Neuchâtel and Geneva observatory trials against the best Swiss houses.
Then on technology. On Christmas Day 1969 Seiko released the Astron, the world's first quartz wristwatch, accurate to five seconds a month where mechanical watches managed that per day. The consequences for Switzerland were catastrophic — employment in the Swiss industry fell by roughly two-thirds over the following decade. Seiko deliberately did not enforce its quartz patents, allowing the technology to spread.
The same year it produced the 6139, among the first automatic chronographs, and it has since introduced Kinetic, Spring Drive — a hybrid regulating a mechanical mainspring electronically, giving a perfectly gliding seconds hand — and its own dive and field lines.
Seiko remains fully vertically integrated, making its own hairsprings, quartz crystals, and even the Zaratsu-polished cases, at price points from under a hundred pounds upward.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Will the glass scratch?
It resists most everyday knocks. Hardlex is a hardened mineral glass — tougher than standard mineral, softer than sapphire.
Does it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
What size strap does it take?
20mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 45.1mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's, though at 38.7mm it sits in the range that suits anyone.
